34.22. RESETTING THE CONTROLLER
When necessary, the controller may be manually reset by holding the STOP button pressed for 30
seconds.
The manual reset will cause the hardware to be configured following new settings.
It is advised to proceed to a manual reset or power off/on cycle after every hardware configuration
modification.
34.23. AUTOMATIC CONNECTION TOPOLOGY
DETERMINATION
The controller offers the capability of automatically determining the connection topology and setting the
voltage checks in accordance.
Related parameters are:
Automatic Topology
Detection
If the automatic topology determination is activated by program parameter, when the engine runs, the
connection topology is tested to be one of below ones during "holdoff timer" period.
If below voltage conditions are met continuously during 3 seconds, then the topology is considered to be
determined.
If the topology cannot be determined during holdoff timer duration, then an "Unknown Topology"
loaddump is generated, and the engine stops after cooldown.
During topology determination phase, if the RUN button is held
pressed, the holdoff timer will not expire and the controller will
try to determine the topology as long as the RUN button is held
pressed.
This feature is especially useful for manual voltage adjustment after a new topology selection.
Available topologies to be determined are:
TOPOLOGY
Voltage
High Wye
314V > L1&L2&L3 > 182V
Low Wye
157 V > L1&L2&L3 > 92 V
High Zigzag
276 V > L1&L2 > 204 V
Low Zigzag
136 V > L1&L2 > 84 V

If this parameter is enabled, when the
engine runs, the controller will detect
the connection topology automatically
